I'd like to highlight a position in the Portfolio tab, to alert me of anything significant such as upcoming ex-dividend date. So far I've been using the notes field for this purpose, but it would be easier if I could display the Note field as it's own column, however IB rep told me it's not possible in Portfolio. Has anyone found a way to add custom column or some other way to highlight a position by giving it another color? TWS does have a column called Dividend Date, but the dates shown are not always accurate and I don't see a way to edit it either. Thanks for any tips.
